Lead Security Engineering - Terminals

About the Role

Logos Space is a Low Earth Orbit (LEO) satellite system designed to serve the connectivity needs of commercial enterprise and government users. We aim to fill a critical market gap by providing resilient, high-performance satellite-based connectivity services globally. The Product and Data Link Security team at Logos Space Engineering ensures network success through unique security and authentication in space communications.

As the Lead Security Engineering - Terminals, you will have technical ownership of the end-to-end security design and delivery of our novel ground-based terminals. This role focuses on the security architecture of terminal systems, including mmWave apertures, complex RF and switching subsystems, and baseband hardware. You will ensure embedded security and secure wireless communication for the ground segment, defining and enforcing security guardrails for Logos' procurement and manufacturing processes.

Responsibilities

• Develop and maintain a comprehensive security strategy and roadmap for ground-based terminal hardware and software interfaces.
• Design and implement RF-related datalink security and secure wireless communication protocols for terminals.
• Conduct thorough threat modeling across terminal hardware components, including mmWave and baseband subsystems, and low-level software interfaces.
• Lead the design and implementation of secure provisioning workflows and key injection for terminal hardware components.
• Ensure alignment with cryptographic standards such as FIPS for terminal security modules.
• Oversee manufacturing security and manage the chain of custody for terminal production to prevent tampering.
• Collaborate with Terminal Hardware and RAN Stack teams to integrate security controls into the terminal architecture.
• Provide technical guidance and mentorship to security engineers, contributing to the overall growth of the security organization.
• Oversee secure boot, firmware security, cryptographic lifecycle management, anti-tampering, and secure onboarding for terminal systems.

Note: This will be a hands-on role with the potential to build a team.

Requirements

• Bachelor's degree in Computer Science, Electrical Engineering, Cybersecurity, or a related field (Master's degree preferred).
• Minimum of 7-10 years of experience in security engineering, with demonstrable experience in designing and implementing security solutions for embedded systems or complex hardware.
• Ability to program in C/C++/Rust and scripting languages like Python.
• Strong knowledge of security principles, best practices, and frameworks (e.g., Zero Trust, defense-in-depth).
• Excellent analytical, problem-solving, and troubleshooting skills.
• Ability to work independently and as part of a collaborative team in a fast-moving environment.

Skills

• Embedded security for ground terminals and network security.
• RF-related datalink security and secure wireless communication.
• Threat modeling across terminal hardware and software interfaces.
• Compliance experience with standards like FIPS, Common Criteria, CSfC.
• Good knowledge of manufacturing security and secure provisioning for terminal hardware.

Preferred Qualifications

• Experience with mmWave apertures, RF/baseband subsystems, and SDR MAC/PHY interactions.
• Relevant security certifications such as CISSP, CISM, or equivalent.
• Experience with automation for hardware security testing tasks.
• Ability and willingness to attain a Top Secret Clearance.
• Experience with 4G/5G RAN systems, wireless infrastructure, SATCOM security, PDCP, IPSEC, or MACSEC.
